2019 GILLIG LOW FLOOR

EQUIPMENT:APPLIANCE:TV/RADIO/SPEAKERS

Gillig, LLC (Gillig) is recalling certain 2019-2024 Low Floor transit buses. The rivet-nut fasteners that secure the TFT flat panel display monitor to the bus ceiling may fail, causing the monitor to detach and fall.

Risk: A monitor that detaches and falls from the ceiling increases the risk of injury.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Gillig, LLC (Gillig) is recalling certain 2019-2023 Low Floor transit buses. The transmission yoke may separate, resulting in driveshaft separation and a sudden loss of drive power.

Risk: A sudden loss of drive power can increase the risk of a crash. Additionally, a disabled bus may require an evacuation procedure in an uncontrolled traffic situation, increasing the risk of injury to passengers.

ELECTRICAL SYSTEM:PROPULSION SYSTEM: CABLES:FASTENER/CONNECTOR

Gillig, LLC (Gillig) is recalling certain 2019-2022 Low Floor electric transit buses. The EV resolver cable connector may experience a loss of electrical connectivity, unexpectedly switching from Drive to Neutral with no warning.

Risk: An unexpected switch to neutral can cause a loss of vehicle propulsion and increase the risk of a crash.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

Gillig, LLC (Gillig) is recalling certain 2014-2021 Low Floor transit buses. The rear-mounted ultracapacitors may allow the engine to be started when the master battery disconnect switch is in the "OFF" position.

Risk: The engine may be started unexpectedly, increasing the risk of injury to anyone nearby the engine compartment during maintenance operations.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Gillig, LLC. (Gillig) is recalling certain 2017-2020 Low Floor vehicles. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

SUSPENSION:REAR

Gillig LLC (Gillig) is recalling certain 2018-2020 Low Floor buses. The rear suspension lower control rods may experience fatigue failure due to stiffened end bushings.

Risk: If the rear suspension lower control rod fails, the bus may have reduced handling and stability, increasing the risk of a crash.

STEERING:HYDRAULIC POWER ASSIST:PUMP

Gillig, LLC. (Gillig) is recalling certain 2013-2020 hybrid and all-electric Low Floor buses equipped with a steering system that uses a high-voltage electric motor and hydraulic pump assembly to provide power steering assist. The shaft coupling between the motor and pump may fail and cause a loss of hydraulic power steering assist.

Risk: A loss of power steering assist may increase the risk of crash.

FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES

Gillig LLC (Gillig) is recalling certain 2018-2020 Low Floor transit buses powered by compressed natural gas (CNG). The thermally activated pressure relief device (PRD) installed on the CNG fuel system may not vent the system when exposed to heat, potentially resulting in the system rupturing.

Risk: If the fuel system ruptures from exposure to heat, there may be an increased risk of injury.

ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS

Gillig LLC (Gillig) is recalling certain 2012-2020 Low Floor buses. The circuit breaker ratings on the DEF Line Heater circuit and the Aftertreatment-Ignition circuit may be higher than the rating for the wire and connector.

Risk: With the improper circuit breaker rating, an electrical short in either of these circuits may increase the risk of a fire.

STRUCTURE:EMERGENCY:ESCAPE/EGRESS/EXIT

Gillig LLC (Gillig) is recalling certain 2018-2019 Low Floor vehicles equipped with a certain batch of glass roof hatches. Temperature and vibration stresses may cause the tempered glass roof hatch to shatter.

Risk: If the tempered glass roof hatch shatters, glass fragments may fall onto passengers, increasing the risk of an injury.
